SECTORAL RANGE
To understand the differences between companies in this sector, it is necessary to look at three sub-sectors.
Building construction, heavy construction, civil engineering construction and specialty trade contractors…
RESIDENTIAL CONSTRUCTION
Residential construction practices, technologies and resources must comply with regulations and codes of practice. Construction costs per square meter for residential buildings vary depending on site conditions, local regulations, and economies of scale. Houses designed as private residences generally cost more and can vary dramatically depending on the use of the qualified customer.
Design and Project:
The structure is designed, floor plans are developed, and a bill of materials is drawn up for projections. Project approval of the building is obtained from the competent authorities. The construction site is cleaned (existing structures, if any, are removed). Ground excavation; Excavation is carried out according to ground survey reports and subsoil information. Foundation concrete and insulation are made according to the approved static project. While the rough structural system continues up to the roof, fine construction begins on some floors. For flat roofs, roof backings or other coverings are installed. Walls are usually constructed with vinyl, wood, or brick veneer, but possibly stone or other materials. Windows are installed, internal plumbing, air conditioning, electrical and gas installations are added. Every stage is inspected by building inspection.
Insulation and interior drywall panels (cement board for wet areas) and assemblies are made to complete walls and ceilings. Bathroom fixtures are installed. The back of the interior walls and ceilings are primed and painted. For wet areas such as bathrooms and kitchens, additional tiles are made on the cement board. Final floor coverings such as flooring, carpet or wood flooring are installed and laid.
QUALITY CONTROL STEPS IN BUILDING CONSTRUCTION
Quality control in building construction is a vital step for the successful completion of a construction project. Quality control steps must be followed and implemented meticulously at every stage of construction. Quality control is of great importance in the planning, design, material selection, application and maintenance processes of construction.
The first step is quality control project planning. Project planning before the start of construction should be prepared meticulously on issues such as material supply processes, labor organization and work schedules.
Another step of the quality control phase is material selection. Choosing the right material is very important for a durable and long-lasting structure. Quality control in material selection includes checking whether it complies with appropriate standards.
During the construction process, quality control should also be applied at the workmanship stage. Workmanship inspection should be carried out by expert teams, and care should be taken to ensure that the work is done in accordance with appropriate standards. Following these steps meticulously is an important factor affecting the outcome of the construction.
THE ROLE OF QUALITY CONTROL IN MATERIAL SELECTION
Quality control in material selection is vital to the successful completion of a construction project. Choosing the right material can affect structural durability, aesthetic appearance and longevity. Therefore, quality control is an indispensable step in the material selection phase.
The quality of materials to be used in construction projects affects project cost, durability and safety. Choosing quality materials can reduce long-term maintenance costs of structures and ensure structural integrity. Therefore, the quality of materials should be considered one of the most important elements of project planning.
Quality control in the material selection process includes determining material properties, examining certificates, and checking whether quality standards are met. In addition, it is necessary to evaluate whether the selected materials meet the requirements of the project.
Selection of quality materials plays a vital role in construction projects as it affects factors such as structural strength, durability and longevity. Therefore, quality control should be given importance and expert opinions should be obtained during the material selection phase.
